Washington (CNN) - Most Democrats say they'd support Hillary Clinton if she wins their party's nomination, but a new national survey indicates only a minority are excited about that prospect.

The CNN/ORC International poll released Sunday also indicates the race for the GOP nomination remains a wide open contest with no obvious frontrunner among the potential Republican White House hopefuls.

In January 2009, as President George W. Bush was days away from leaving the White House, the unpopular President's favorable rating stood at 35% in a CNN/ORC International survey. The man who was succeeding him, Barack Obama, was fresh from his historic 2008 presidential election victory and had a 78% favorable rating among Americans.

Washington (CNN) - Twenty years after the start of the O.J. Simpson murder case, attitudes towards Simpson and towards race relations in the country have dramatically changed, according to a new national poll.

Monday night's release of the CNN/ORC International survey comes just a few days before 20th anniversary of the murders of Nicole Brown Simpson, the former football star and actor's ex-wife, and of Ronald Goldman. The case against Simpson and the ensuing more than eight-month-long criminal trial, dubbed the "trial of the century," engrossed the nation. Simpson was eventually acquitted.

Program note: Hillary Clinton will discuss her memoir "Hard Choices" in a town hall meeting at the Newseum in Washington at 5 p.m. ET on June 17. The former secretary of state, senator and first lady will take questions from moderator Christiane Amanpour, CNN's Chief International Correspondent, and members of the audience. The town hall will be simulcast on CNN International and CNN en Espanol.

Washington (CNN) - With her much anticipated memoir hitting bookstores on Tuesday, coverage of Hillary Clinton is exploding this week, from the broadcast networks to cable news to social media.

Polling indicates that the former secretary of state, who says she'll probably decide next year whether she'll make another run for the White House, would instantly become the overwhelming frontrunner for the 2016 Democratic presidential nomination.

Washington (CNN) - Nearly six in ten Americans give President Barack Obama a thumbs-down on how he is handling the Veterans Affairs controversy, according to a new national poll.

But a CNN/ORC International survey released Tuesday indicates that the scandal at VA hospitals doesn't seem to be affecting the President's overall approval rating, which remains at 43%, identical to the last CNN poll conducted a month ago. The survey also indicates that Obama scores some of his highest numbers on the environment and terrorism, two other issues in the spotlight this week.

Washington (CNN) - A majority of Americans want to keep the federal health care law as is, or make some changes to improve it, according to a new national poll.

But a CNN/ORC International survey released Sunday also indicates public attitudes have been largely unaffected by news that 8 million people have enrolled in health insurance plans under the Affordable Care Act, known as Obamacare.

Washington (CNN) - She's still the overwhelming front runner in the race for the 2016 Democratic presidential nomination, but according to a new national poll Hillary Clinton's support has slightly deteriorated since the beginning of the year.

And a CNN/ORC International survey released Tuesday morning also indicates that while the hunt for the Republican nomination remains wide open at this very early point, former Florida Gov. Jeb Bush is now tied with Sen. Rand Paul of Kentucky at the top of a crowded list of potential contenders.

(CNN) – Americans are increasingly concerned about the ongoing situation in Ukraine, but few express support for using U.S. military force in that county, according to a new national survey released Monday.

A CNN/ORC International poll also indicates that even if economic and diplomatic efforts fail in curbing Russia's aggression in the region, Americans still oppose U.S. military involvement.

Washington (CNN) – A small edge right now in a key indicator of the midterm elections could lead to a big advantage for the Republicans over the Democrats come November.

That's the suggestion from a new CNN/ORC International poll, that also indicates that President Barack Obama's lackluster approval ratings and pessimistic perceptions about the economy could also make 2014 a good year for the GOP at the ballot box.

Monday's the last day of open enrollment to sign up for health insurance and avoid a penalty, through exchanges set up as part the federal health care law, formally known as the Patient Protection and Affordable Care Act.

While there are sharp political disagreements over the measure, one thing's for sure: there has been more polling on the 2010 law than any other legislation in recent years. And the measure should be a major issue in the 2014 midterm elections, just as it was in the 2010 midterms and the 2012 presidential contest.
